Japanese Quick-Disconnect Hose Couplings for Air
A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them if you need frequent access to a line. All Japanese plugs are compatible with any of the Japanese sockets, regardless of the pipe size or barbed hose ID. Plugs and sockets are zinc-plated steel, which is strong and durable. They have fair corrosion resistance, so they should be used primarily in dry environments.
Plugs are also known as nipples.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

Metal Push-On Barbed Hose Fittings for Air and Water
Fittings have sharper barbs than standard barbed hose fittings to grip rubber push-on hose with no clamps or ferrules required. The more you pull on the fittings, the tighter the hose will grip.
Brass fittings are softer than other metal fittings, so they’re easier to thread together. They have good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance, so they’re the best choice for high-humidity environments.Fittings with a threaded end are also known as hose nipples.Hose connectors are also known as hose menders and splicers. Use them to join two lengths of hose or to repair damaged hose.
The optional installation tool (sold separately) allows you to connect large quantities of barbed fittings to push-on hose. Use the built-in cutter to squarely cut the hose without fraying. Next, lubricate either the push-on hose, fitting or both. Then, clamp the hose into the tool’s vise and apply light pressure on the handle to drive into the fitting.
Note: To ensure proper connection, the barbed end has to be pushed in all the way, with the hose end concealed by the ring.

45° Flared Fittings for Copper and Brass Tubing
- Temperature Range: -65° to 250° F
- Tubing: Use with seamless brass and copper that meets ASTM B280
No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They require a nut (sold separately) for each tube end. Fittings are also known as refrigeration and SAE fittings. They are brass for good corrosion resistance.
NPTF (Dryseal) threads are compatible with NPT threads.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

Made to tighter tolerances than other compression fittings, these are designed for high-precision applications. They are also known as instrumentation fittings and flareless fittings. They come with a nut and a single sleeve (ferrule). The sleeve bites into tubing as you tighten the nut to create a strong seal. The nut has a molybdenum disulfide coating that acts as a lubricant for easy installation. Fittings are brass for good corrosion resistance.
